Making Space: How the Brain Knows Where Things Are
Knowing where things are seems effortless. Yet our brains devote tremendous computational power to figuring out the simplest details about spatial relationships. Going to the grocery store or finding our cell phone requires sleuthing and coordination across different sensory and motor domains. Making Space" traces this mental detective work to explain how the brain creates our sense of location. But it goes further, to make the case that spatial processing permeates all our cognitive abilities, and that the brain s systems for thinking about space may be the systems of thought itself. Our senses measure energy in the form of light, sound, and pressure on the skin, and our brains evaluate these measurements to make inferences about objects and boundaries. Jennifer Groh describes how eyes detect electromagnetic radiation, how the brain can locate sounds by measuring differences of less than one one-thousandth of a second in how long they take to reach each ear, and how the ear s balance organs help us monitor body posture and movement. The brain synthesizes all this neural information so that we can navigate three-dimensional space. But the brain s work doesn t end there. Spatial representations do double duty in aiding memory and reasoning. This is why it is harder to remember how to get somewhere if someone else is driving, and why, if we set out to do something and forget what it was, returning to the place we started can jog our memory. In making space the brain uses powers we did not know we have."

Principles and Applications of Powder Diffraction
English | Physics | 5. September 2008 | ISBN-10: 1405162228 | 400 pages | pdf | 10 mb
Powder diffraction is one of the primary techniques used to characterize materials, providing structural information even when the crystallite size is too small for single crystal x-ray diffraction methods.

Principles and Applications of Powder Diffraction
There has been a significant increase in the application of powder diffraction in recent years, both in research and manufacturing, fuelled by improved instrumentation, data processing and awareness of the information that can be obtained. Powder diffraction allows for rapid, non-destructive analysis of multi-component mixtures without the need for extensive sample preparation. This gives laboratories the ability to quickly analyse unknown materials and perform materials characterization in such fields as chemistry, materials science, geology, mineralogy, forensics, archaeology, and the biological and pharmaceutical sciences.

This book provides a concise introduction to modern powder diffraction methods with particular emphasis on practical aspects. It covers the background theory of diffraction in a form approachable by those with an undergraduate degree. Whilst individual chapters are written as stand alone sections, the text is sufficiently focused so that it can be read in its entirety by the non-specialist who wants to gain a rapid overview of what they can do with modern powder diffraction methods.

Study and Design of Differential Microphone Arrays

FREEDownload : Study and Design of Differential Microphone Arrays

Jacob Benesty, Jingdong Chen, "Study and Design of Differential Microphone Arrays"
English | 2013 | ISBN-10: 364233752X, 3642427561 | 180 pages | PDF | 6 MB

Study and Design of Differential Microphone Arrays
Microphone arrays have attracted a lot of interest over the last few decades since they have the potential to solve many important problems such as noise reduction/speech enhancement, source separation, dereverberation, spatial sound recording, and source localization/tracking, to name a few. However, the design and implementation of microphone arrays with beamforming algorithms is not a trivial task when it comes to processing broadband signals such as speech. Indeed, in most sensor arrangements, the beamformer output tends to have a frequency-dependent response. One exception, perhaps, is the family of differential microphone arrays (DMAs) who have the promise to form frequency-independent responses. Moreover, they have the potential to attain high directional gains with small and compact apertures. As a result, this type of microphone arrays has drawn much research and development attention recently. This book is intended to provide a systematic study of DMAs from a signal processing perspective. The primary objective is to develop a rigorous but yet simple theory

for the design, implementation, and performance analysis of DMAs. The theory includes some signal processing techniques for the design of commonly used first-order, second-order, third-order, and also the general Nth-order DMAs. For each order, particular examples are given on how to form standard directional patterns such as the dipole, cardioid, supercardioid, hypercardioid, subcardioid, and quadrupole. The study demonstrates the performance of the different order DMAs in terms of beampattern, directivity factor, white noise gain, and gain for point sources. The inherent relationship between differential processing and adaptive beamforming is discussed, which provides a better understanding of DMAs and why they can achieve high directional gain. Finally, we show how to design DMAs that can be robust against white noise amplification.

Blood and Violence in Early Modern France

FREEDownload : Blood and Violence in Early Modern France

Stuart Carroll "Blood and Violence in Early Modern France"
Oxford University Press | 2006-07-03 | ISBN: 0199290458 | 384 pages | PDF | 5 MB

Blood and Violence in Early Modern France
The rise of civilized conduct and behaviour has long been seen as one of the major factors in the transformation from medieval to modern society. Thinkers and historians alike argue that violence progressively declined as men learned to control their emotions. The feud is a phenomenon associated with backward societies, and in the West duelling codified behaviour and channelled aggression into ritualised combats that satisfied honour without the shedding of blood. French manners and codes of civility laid the foundations of civilized Western values. But as this original work of archival research shows we continue to romanticize violence in the era of the swashbuckling swordsman. In France, thousands of men died in duels in which the rules of the game were regularly flouted. Many duels were in fact mini-battles and must be seen not as a replacement of the blood feud, but as a continuation of vengeance-taking in a much bloodier form. This book outlines the nature of feuding in France and its intensification in the wake of the Protestant Reformation, civil war and dynastic weakness, and considers the solutions proposed by thinkers from Montaigne to Hobbes. The creation of the largest standing army in Europe since the Romans was one such solution, but the militarization of society, a model adopted throughout Europe, reveals the darker side of the civilizing process.

Play Matters

Play Matters (Playful Thinking series) by Miguel Sicart
2014 | ISBN: 0262027925 | English | 176 pages | PDF | 7 MB

Play Matters
What do we think about when we think about play? A pastime? Games? Childish activities? The opposite of work? Think again: If we are happy and well rested, we may approach even our daily tasks in a playful way, taking the attitude of play without the activity of play. So what, then, is play? In , Miguel Sicart argues that to play is to be in the world; playing is a form of understanding what surrounds us and a way of engaging with others. Play goes beyond games; it is a mode of being human. We play games, but we also play with toys, on playgrounds, with technologies and design. Sicart proposes a theory of play that doesn't derive from a particular object or activity but is a portable tool for being–not tied to objects but brought by people to the complex interactions that form their daily lives. It is not separated from reality; it is part of it. It is pleasurable, but not necessarily fun. Play can be dangerous, addictive, and destructive. Along the way, Sicart considers playfulness, the capacity to use play outside the context of play; toys, the materialization of play — instruments but also play pals; playgrounds, play spaces that enable all kinds of play; beauty, the aesthetics of play through action; political play — from Maradona's goal against England in the 1986 World Cup to the hactivist activities of Anonymous; the political, aesthetic, and moral activity of game design; and why play and computers get along so well.

Physical Approaches to Biological Evolution

Mikhail V. Volkenstein, "Physical Approaches to Biological Evolution"
1994 | pages: 402 | ISBN: 3642787908 | DJVU | 4,5 mb

Physical Approaches to Biological Evolution
"Mr. Wolkenstein's , whether or not it proves to give the ultimate truth on the matters with which it deals, certainly deserves, by its breadth and scope and profundity, to be considered an impor­ tant event in the philosophical world." This is a quotation from an introduction written by Bertrand Russell for Ludwig Wittgenstein's Tractatus Logico-Philosophicus. I exchanged only name and subject. As for the rest, I could continue quoting Russell, but I would rather say something myself. As Wittgenstein did with formal logic, Wolkenstein rectifies our views on how to approach the logic of life from a formal theoretical basis. Many bio­ logists do not believe that their subject lends itself to the scrutiny of physical theory. They certainly admit that one can simulate biological phenomena by models that can be expressed in a mathematical form. However, they do not believe that biology can be given a theoretical foundation that is defined within the general framework of physics. Rather, they insist on a holistic approach, banning any reduction to fundamental principles subject to physical theory.
